Umbilical arterial (UA) Doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia.
When using your fetal doppler it is suggested that you use it in short intervals, infrequently, and following the first trimester. As a general rule an exam with a fetal doppler should never last longer than 10 minutes. If you don't find the heartbeat in this period of time, take a break.
